This is the best iPhone dock I have seen and it should be landing around April. Designed by Casey Hopkins this Kickstarter project got it's $75,000 in funding in just 8 hours and they ended up raising over $700,000. The dock is made out of one piece of aluminium and the dock connecter has been redesigned so that removal is a breeze. It has also been designed so that you can use it, with or without a case.
I can't wait to get one.
